JAMES E. SNEVELY, OF SALT LAKE CITY, UTAH.

BRUSH-MAKIN G MACHINE Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed June 19, 1907. Serial No. 379,723.

To all whom it may concern:

1 Be it known that I, JAMES E. SNEVELY, a citizen of the United States, residing at Salt Lake City, in the State of Utah, have invented a new and useful Brush-Making Machine, of which the following is a specification.

The invention relates to machines for making brushes and especially feather dusting brushes.

Among the objects of the invention are to provide means for readily inserting, adjusting and removing brush heads to be operated upon and to provide power-operated means for clipping off the ends of quills after the feathers are mounted on the brush heads.

The foregoing and other characteristics and advantages of the invention will be hereinafter fully set forth in connection with a detailed description of the accompanying drawing, which illustrates an exemplifying structure embodying the invention.

Figure 1 is a front side elevation; Fi 2 a partial plan view on an enlar ed scale; Fig. 3 a detail of the tail-stock acjusting lever,

\ partly in section; Fig. 4 a longitudinal section through the tail-stock and spindle, showing the shifting collar; Fig. 5 a vertical section on line AA, Fig. 1; Fig. 6 a detail view from the position indicated by section line B-B, Fig. 5; Fig. 7 a detail crosssection of the clamp for the cutter-carrier; Fig. 8 a detail enlarged View, in plan, of the cutter and guide; and Fig. 9 a detail vertical sec tionat C-C, Fig. 8.

Reference numeral 1 designates the frame, car ing spindles 23 for the head and tailstoc {8- respectively. Near the bottom the frame carries shaft 4, on which is mounted the horizontally-spoked drum 5. This drum provides a foot drive for the machine, but can, if desired, be replaced by a power drive pulley. Pulleys 6 and belt 7 connect spindle 2 revolubly with the driving shaft, and ulleys 8 and belt 9 similarly connect rile 3 with the driving shaft. The headstock 10 is slidably mounted within its spindle and secured in adjusted position by hand-nut 11. This adjustment is for bringing the brush head in convenient relation to the winding mechanism, as will hereafter appear. Ordinaril when working on a iven size of brus isturbed, the brush heads bein inserted and removed by moving the tail-stock, as

i will appear.

the head-stock is not' The tail-stock 12 (see Figs. 2 and 4) telescopes in spindle 3, the latter being slotted on opposite sides at 13. A pin 14 passes through a hole in the tail-stock. Collar 15 surrounds the spindle and has sockets receiving the ends of pin 14. Shifting lever 16 has a ring 17 formed at about its center. This ring is engaged by trunnions 18 on collar 15. The inner end of the lever is ivoted at 19 to link 20, in turn pivoted to t 1e frame at 21, and the outer end of the lever is provided with a pawl 22, pivoted to the lever at 23,

and having a hand-piece 24 pressed outwardly by spring 25 to hold the pawl in engagement with a ratchet'26. The brush head 27 is held between the head and tail-stocks, which are provided with suitable jaws to rotate the head.

In inserting a brush head lever 16 is moved to the right, as in Fig. 2, by depressing handpiece 24 and withdrawing pawl 22 from the rack, thus moving tail-stock 12 away from head-stock 10. The brush heads are usually bored to receive the brush handles, and the bored end is placed over the end of the tailstock and the latter then moved to the left until the brush head is brought into engage ment with the head-stock at its other end. By releasing hand-piece 24 the lever is locked in position, and u on rotation of the drivingshaft 4 the brush lead is rotated.

The brush heads are provided with grooves 28, in which the quills 29 of the feathers are bound by one or more turns of wire or strands of other material 30 (see Fig. 9). The wire is carried in acoil on spool 31, passes over idler pulley 32 and guide roll 33 at the top of the frame, which'has any desired number of grooves 34, over which the wire is run to direct it to the desired groove of the brush head. The wire is nailed or otherwise suitably connected to the brush head at the start, and the head being then rotated the quills 29 of the feathers are laid across the groove in the head and bound in position by the wire, which is run off of spool 31 by the rotation of the brush head. The wire may be cut and bound at the completion of each row of feathers, or it may run from one groove to the other until the brush is completed and be then bound by nailing or in any other suitable manner.

Heretofore brushes of this class have generally been made by hand, and it has been customary to clip off by hand the protruding Sleeve 44 of the cutter carrier is slidably ends 29 of the quills after each row of feathl ers is completed. I have devised means for performing this operation automatically durmg the winding process, which will now be described.

Splined shaft 40 is revolubly mounted in the frame, preferably at a lower level than the brush head, and driven by means of pulleys 41 and belt 42 from the driving-shaft. Carrier shaft 43 which is irrevoluble, is carried on the frame parallel with shaft 40.

mounted on shaft 43 and has two arms 45, the ends of which encircle shaft 40 and are adapted to slide upon it. Between arms 45, bevel gear 46 is feathered on shaft 40 so that it revolves with the shaft but is free to move longitudinally thereon. Also between arms 45 the inner end of cutter arm 47 is pivotally mounted on shaft 40. The cutter arm has an arc-shaped supporting rod 48, which passes through a hole in the carrier sleeve and is encircled by a helical spring 49, compressed between the arm and the sleeve, which serves to urge the cutter arm upward. Rod 48 is provided with a notch 50 adapted to be engaged by the end of the plunger 51, which is reciprocally mounted in a socket 52 formed in the carrier sleeve and a lug 53 on one of arms 45. The plunger is urged to engage the notch by spring 54, compressed between lug 53 and collar 55 on the plunger.

To remove the cutter arm from operative relation to its work, it is simply moved downward, compressing the spring 49 until notch 50 in rod 48 comes opposite the plunger, whereupon plunger 51 enters the notch under influence of its spring 54 and retains the cutter arm in depressed, inoperative position.

The shaft end of the cutter arm 47 has a lug 55 which carries revoluble pinion 56, engaging gear 46. Lever 57 is fulcrumed at 58 on the cutter arm and at one end has a slot 59 engaged by crank pin 60, carried by pinion 56. The movable cutter 61 is pivoted at 62 on the cutter arm, and has at its inner end a slot 63 which is engaged by a pin 64 carried by the outer end of lever 57. On the outer end of the movable cutter is the blade 65, the cutting edge of which rests against the fiat bottom face of the fixed cutter 66, which is secured to the end of the cutter arm above the yoke-shaped depression 67. Opposite the cutter arm is a guide 68 which has a beveled end 69, between which and the fixed cutter the projecting ends 29 of the quills pass as the brush head rotates. The guide is carried by the stem 70 reciprocally mounted in lugs 71 on the cutter arm and held in the position shown in Fig. 8 by a spring 72 compressed between one of the lugs and a pin 73 carried by the stem. The upper fiat face 74 of the guide provides a bottom bearing surface for the movable cutconnect-ed by a link 98 with rod 83.

ter blade, and at the end an upward projection 7 5 formed on the guide adjacent to the end of the movable blade serves to prevent the operator from getting his fingers into contact with the cutting apparatus.

Evidently as shaft 40 rotates gear 46 revolves, rotating pinion 56 and pin 60, which causes lever 57 to oscillate, and by means of pin 64 the movable cutter 61 is oscillated, moving the cutter blade 65 back and forth under the fixed blade 66 and shearing off the projecting ends of the quills as the brush head rotates and brings them successively to the cutter. Aloop 76 formed in guide 68 affords means for grasping and retracting the cutter arm from the work.

A portion of carrier sleeve 44 is cut away at one side, and in the recess thus formed a clamping member 80 (see Figs. 5, 6 and 7) is pivoted at 81 so that it bears against shaft 43. The upper ends of the clamp and the sleeve project above the shaft as at 82 and a clamping rod 83 passes through these members, being secured to the clamp 80 by a pin 84. At its rear end the rod has a collar 85 and a spring 86 compressed between the collar and the projection of the sleeve normally urges the clamp into engagement with shaft 43 and prevents the cutter carrier from moving thereon. Collar 85 on rod 83 has a lateral finger 87, which engages one arm 88 of the bell crank 89 pivoted to one of the carrier arms 45 at 90, and whose other arm 91 underlies a finger 92, projecting from the upper end of plunger 51, through a slot in arm 45.

Shifting lever 94 for the carrier is ivoted to it at 95 and at its rear end is slotte to embrace a pin 96 carried b the frame. The lever carries a pivoted re easing member 97 Now supposing that the cutter'arm has been depressed and is retained in depressed position in the manner which has been described, to release it hand-piece 97 on lever 94 is grasped, which pulls link 98 and rod 83; finger 87 carried by the rod engages arm 88 of bell crank 89, rotating the bell crank; the other arm 91 of the bell crank raises finger 92, carried by plunger 51 retracting the plunger from notch 50 in curved rod 48, whereupon cutter arm 47 rises to operative position with fixed cutter 66 resting against the brush head under the influence of spring 49. At the same time movement of rod 83 withdraws clamp 80 from engagement with shaft 43, freeing the carrier on its shaft, and by lateral movement of lever 94 the whole carrier and its related parts are shifted on their shafts 4043 to bring the cutter in proper relation to the groove on the brush head on which it is desired to work.

Many obvious modifications may be made in the structure shown and described without departing from my invention.
